IMPLEMENT FOR NNITIITG STRIPS OF MATERIAL.

Application filed April 11, 1924. Serial No. 705,776.

T 0 all wit-0122 it mayconcern:

Be it known that I, ANNA LAUER, a citizen of the United. States,residing at New York, in the county of Queens and State of New York, have invented new and useful Improvements in Implements for Uniting Strips of Material, of which the following is a specification.

My invention relates to implements em: ployed to join strips of cloth together for the subsequent weaving into rag carpets and the like, and the method of so joining them,

and the object of my invention is to provide a simple, easily operated device which will quickly join strips of cloth together in the manner shown and described herein, without the use'of thread, consisting in inter ooping the adjoining ends of said strips in a flattened manner to avoid bulky connections, such as ordinary knots, the latter being undesirable for the proper weaving of said carpets and otherwise obj ectional for reasons of unsightliness.

I have observed that strips of cloth joined together by my method and with the use of my implement can be woven into carpets or rugs quite as readily as the strips heretofore joined together by the use of needle and thread, said connections being amply secure, more quickly and conveniently effected and proving to be equally inconspicuous after weaving.

Further objects of the invention are hereinafter set forth.

I attain these objects as fully set forth in detail in the accompanying specification and drawings forming a part hereof, in which latter I have illustrated suitable embodiments of my invention.

Referring to such drawings: 7

Fig. 1 is a perspective view of my implement mounted upon a supporting base.

Fig. 2 is an elevation, partly in section, of same with a modified form of base and manner of securing the implement thereto.

Fig. 2 is an elevation, on a reduced scale, of a modified form of the invention.

Fig. 3 is an elevation of my implement as adjacent end portions of two of said strips of material, united in the manner set forth in Figs. 4, 5, 6, 7 and 8 and prior to subse quently pulling the strips into a tight connectlon.

Fig. 10 is a similar view of the final ti glitened connection, and

Fig. 11 is a view similar to Fig. 10 but somewhat loosened to illustrate more clearly the manner in which the ends are looped together to unite them.

In Fig. 1 I have shown a flat upwardly extending blade 2 terminating in a sharp point 3 the tapering sides 4, leading to the point, being ground to provide knife edges terminating at their lower extremities in shoulders 5. An eye 6 adjacent the pointed end of the blade is herein shown in the form of an isosceles triangle, the two long sides of which parallel the said knife edges. The eye 6, its relative position and its configuration, are important adjuncts to the proper functioning of the device as will be more fully pointed out hereinafter.

The lower end of the blade 2 may be equally divided to form oppositely extending lugs 7, bent at rightangles to the blade, and serving by means of screws 8 to secure the blade 2 in a perpendicular position on a supporting base 9.

In Fig. 2 the base employed is in the form of a standard 10 and instead of the lugs 7 the lower end of the blade is tapered to provide a pointed extension 11 adapted to be J forced into the standard 10 which latter is made of wood or other suitable material.

Shoulders 12 limit the penetration of the extension 11, serve as guides to ensure a perpendicular axis for the blade 2 and take the downward thrust inherent to the operation of the implement.

The blade 2 may be mounted, as in Fig. 3,,

on a screw clamp 13 so that the implement may be secured to the edge of a table in a well known manner.

As in Fig. 2 the blade may consist of two members, pivoted together as at 14L, one of said members being provided with. a projection 15 and the other with a recess 16 adapted to snap together in a spring-like manner when the blade is in an upright position for use, and conversely to be disengaged so that the blade may be folded to one side to prevent accidental injury from same when not in use.

The operation of oining together two pieces of material, such for example as cloth, consists of the following successive steps as shown in Figs. 4, 5, 6, 7 and 8.

Referring to Fig. 4. a strip A, adjacent one end thereof, is thrust downwardly, the point 3 penetrating it and the continued downward movement of the strip until it seats on the shoulders 55, resulting in the slitting of said strip through its longitudinal axis as at 1'7, by the knife edges 4, the eye 6 passing through said slit.

Following this treatment of the first strip, a second one B is siu'iilarly mounted on the blade. being likewise slitted as at 18, the two strips now extending in opposite directions with their slitted ends engaging each other in overlapping relation as shown in Fig.

A portion of the end of strip A, opposite to the end which has been slitted, is then inserted in the eye (5' through the wide part thereof as shown in Fig. 6 and the two strips are then slipped otf of the blade 2. the eye 6 dra vin the end engaged thereby through the slits l7 and 18 as shown in Fig. 7, the acute angle of the eye 6 adjacent the point 3 providing sutlicient frictional engagement with the portion of the strip inserted therein to accomplish this result, the said end portion being drawn entirely through the slits 17 and 18 as in Fig. 8, and subsequently completely out of engagement with the eye 6. This end can now be manually drawn on through the said slits by the operator as in Fig. 9, until finally drawn tight as in Fi 10 resulting in a. flat firm connection.

fter a number of these strips are so joined together they form a continuous strand suitable for subsequent weaving in the manner desired.

Various modifications within the scope of the appended claim may be made without departing from the spirit of my invention.

I claim:

An implement for joining the ends of two strips of flexible material comprising a flat pointed knife-blade, shoulders integrally formed on the opposite edges of the blade in horizontal alignment to limit its penetration, an eye in said blade extending upw rdly from the plane of said shoulders, the sides of said eye converging toward the point of the blade to form an acute angle in the top of the eye, and a downwardly eX- tending pointed portion on said blade formed to provide shoulders and adapted in combination with said shoulders to secure said blade to and position it on a supporting member.

ANNA. LAUER.
